Ingredients Insights

Steelhead Trout:
If you haven’t cooked with steelhead before, think of it like salmon’s delicious, slightly less expensive cousin. It has a similar rich, buttery texture and flavor. It’s also full of healthy omega-3s and cooks up beautifully in the oven.

Butter:
A classic base for any good sauce. It melts into the fish, keeping it moist and adding a luscious, silky finish.

Garlic:
Fresh minced garlic is best here for its strong, aromatic punch. It infuses the butter, creating a deeply flavorful sauce.

Lemon:
Brightens the entire dish. The acidity balances the richness of the butter and fish perfectly. I love adding extra slices on top before baking for even more citrusy aroma.

Red Pepper Flakes:
Just a pinch for subtle heat. It cuts through the richness and keeps you coming back for bite after bite.

Parsley:
Adds that final fresh, herbal note. It’s simple but really finishes the dish beautifully.

Tips and Tricks

Don’t Overcook: Steelhead is best when it’s just cooked through and still moist. Keep an eye on it so it stays flaky and tender.
Room Temperature Fish: Letting the fish sit at room temperature for 10–15 minutes before cooking helps it cook more evenly.
Customize the Sauce: Add a bit of grated Parmesan, fresh rosemary, or lemon zest if you want to get a little fancy.
Use Fresh Lemon: Freshly squeezed lemon juice is a must—it’s so much brighter than bottled.
Check for Bones: Run your fingers over the fillet before cooking and remove any pin bones with tweezers.

Make Ahead Tips

This dish is so quick to make that you don’t really need much advance prep, but you can:

Mince the garlic ahead of time and store it in the fridge.
Slice your lemon and chop the parsley so everything is ready to go.
Even the butter can be mixed with garlic and red pepper flakes ahead of time, so you just have to spread it on when you’re ready to cook.

It’s perfect for nights when you want something homemade but don’t have the energy for lots of chopping.

Serving Suggestions

This Lemon Garlic Butter Steelhead is really versatile.

Serve it with roasted or steamed veggies like asparagus, green beans, or broccoli. It’s fantastic with mashed potatoes, buttered rice, or a simple pasta tossed in olive oil and Parmesan.

For something lighter, try it over a crisp green salad with a lemon vinaigrette. The leftover fish is also amazing flaked onto salads, folded into wraps, or even scrambled into eggs the next morning.

Storage

Refrigerator:
Store any leftover fish in an airtight container in the fridge for up to 3 days.

Reheating:
Gently reheat in a low oven or in a covered pan over low heat to avoid drying it out. Or serve it cold over salads.

Freezer:
I usually don’t recommend freezing cooked fish like this, as the texture can suffer. It’s best enjoyed fresh or within a couple of days.

FAQs

What’s the difference between steelhead trout and salmon?
Steelhead looks and tastes very similar to salmon but tends to be a little milder and often costs less. It’s a fantastic alternative if you want that rich, buttery flavor without the higher price tag.

Is farmed steelhead sustainable?
When sourced from a well-managed fishery, yes! The steelhead in this recipe is certified as a Best Choice by Monterey Bay’s Seafood Watch.

Can I use salmon instead?
Absolutely. This recipe works beautifully with salmon fillets. Just adjust the cooking time as needed, depending on thickness.

How do I know when it’s done?
The fish should be opaque and flake easily with a fork. If you have a thermometer, aim for an internal temp of 135–140°F for perfectly cooked, moist fish.
